As water molecules are heated, their average speed increases. This increase in speed is due to the increase in kinetic energy of the molecules, causing them to move faster. This relationship is described by the kinetic theory of gases.
When FeSO4·7H2O is heated strongly, it loses its water molecules and forms anhydrous FeSO4. The color changes from blue to white or pale green due to the removal of water molecules, and the compound becomes anhydrous iron(II) sulfate (FeSO4).
If You're suggesting what happens to water when heated then the answer is: Water molecules speed up by the heat increasing it's temperature and when it reaches 100 Degrees the molecules are so fast that the water turn into a gas (Steam) But if you are just asking about the temperature then; When you heat water the temperature also increases.
Water is highly cohesive. Its molecules tend to resist increases in their motion. When water is heated, some of the energy is used to disturb the hydrogen bonds between neighboring molecules.
In general, most materials expand when heated due to the increase in kinetic energy of their molecules. However, there are exceptions, such as water, which contracts when heated from 0°C to 4°C due to changes in its molecular structure. This anomaly is known as the "anomalous expansion of water."
As water molecules are heated, their average speed increases. This increase in speed is due to the increase in kinetic energy of the molecules, causing them to move faster. This relationship is described by the kinetic theory of gases.
what changes take place when water is heated or cooled
the molecules evapourate
When ice changes to water, the speed of the water molecules increases. In the solid state as ice, the molecules are held in a rigid structure and have minimal movement. As heat is added, the molecules gain energy, causing them to vibrate faster and break free from their rigid arrangement, resulting in the molecules moving more freely in the liquid state.

Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.
For the small change of temperature between where water exists as a liquid and as a gas the molecules will stay the same size. What changes is the speed the molecules are moving at. Hotter is faster. When moving fast enough (having absorbed enough energy) the molecules break away from the liquid to become water vapour.
As the water in the beaker is heated from 10°C to 90°C, the water molecules gain kinetic energy and begin to move faster. This increased movement causes the water molecules to spread apart, decreasing the density of the water. Eventually, the water at 90°C will reach its boiling point and some of the molecules will transition into the gaseous state as steam.
The liquid molecules are transformed in gas molecules.
